Emollient

Role details

*What are emollients used for?*

Emollients are used in moisturisers to help dry skin gain and retain moisture. All organs, including the skin, need to repair and regenerate in order to stay healthy. The biological reactions that take place to facilitate this all require the presence of water. If skin is too dry, its ability to repair and regenerate itself is compromised.

Also, as skin gets dry, it becomes prone to tightness and irritation. In the long term, dry skin will contribute to the formation of fine lines and wrinkles. Dry skin is also more susceptible to damage such as from sun exposure or harsh detergents.

Often, the word _emollient_ is used interchangeably with _moisturiser._ Technically speaking, emollient is used to refer to the single ingredient, whereas moisturiser refers to the finished product, which combines multiple ingredients.

*How do they work?*

Emollients help to moisturise through the following properties:

*Occlusion:* Providing a protective layer on top of skin to seal in moisture and prevent it from evaporating

*Humectant:* Increasing the water-holding capacity of skin and drawing water into skin

*Lubrication:* Providing slip and glide across skin for a smoother feel
